MOBILE COMMUNICATION SYSTEM AND METHOD FOR RECEIVING/TRANSMITTING CHANNEL THEREOF

摘要

An embodiment of the present invention in a time division duplexing (TDD) wireless communication system consisting of a broadband network via a carrier aggregation and including a first cell and a second cell, in the case that the TDD uplink-downlink settings of the aggregated carriers are different according to each carrier, provides a terminal communication method comprising steps of: receiving a physical downlink shared channel (PDSCH) via the second cell; and transmitting, to a base station, information including a success or not in receiving the PDSCH. The step of transmitting, to the base station, the information including a success or not in receiving the PDSCH includes a step of transmitting the receipt success or not at a physical uplink control channel of the first cell. According to the embodiment of the present invention, the control information on data can be transmitted from the terminal by providing a control information transmitting method in the TDD wireless communication system consisting of the broadband network via the carrier aggregation.
